The "DC-10 as water bomber" thread reminded me of an article
I read recently, and I was able to dig it up. The following article appeared in the August 2003 issue of Boeing Frontiers, the internal Boeing company magazine: Water bombs Boeing invention could make C-17 a firefighter BY RICK SANFORD A beach ball-sized water bomb may some day take the danger out of aerial firefighting and greatly reduce the time and cost to extinguish a blaze. The concept stems from a program sponsored by the Boeing Chairman's Innovation Initiative, which provides the context for Boeing people with great ideas to create new businesses. An idea from William Cleary, a project manager in the Boeing Integrated Defense Systems Advanced Airlift and Tanker organization, involves an out-of-the-box method of fighting fires. Dropping water or fire retardant on a fire requires conventional aircraft to swoop dangerously low in order to deliver their cloud of liquid where needed. Heat and thermal winds make the chore challenging, dangerous and often less effective. "The sooner you can knock a fire down, the better," said Cleary, a designer of the proposed water bomb system. "In May of 2000, New Mexico's Los Alamos fire burned for three days before exploding into a 500-square-mile behemoth." So how does a beach ball do the trick? The system, called Precision Aerial Fire Fighting, uses up to 2,800 biodegradable, faceted spheres stacked on pallets within cardboard containers. This delivery technique is similar to the way U.S. Air Force C-17s airdropped yellow humanitarian ration packages to Afghanis in 2001. The unit's spherical shape minimizes airflow resistance. Each sphere contains 50 pounds of water and easily remains intact while it falls true to target. The spheres burst on impact at the heart of the fire. A single C-17 PAFF mission could airdrop 140,000 pounds of water on multiple "hot spot" targets-equivalent to nearly 100 helicopter deliveries. "What's more," said Cleary, "the C-17 can airdrop from 1,000 to 2,000 feet above ground level using precision navigation and airdrop instrumentation, remaining safely away from the fire and winds," he said. "If a C-17 were used, this delivery system is remarkably cost effective, and the savings in lives and property make it an interesting possibility for the Air National Guard." As with today's aerial firefighting, a ground safety fire commander would ensure ground personnel are clear of the airdrop zone and would direct airdrop targeting. Advantages of C-17 Precision Aerial Fire Fighting 1) Safe aircraft altitude for airdrops 2) Use of collapsible, biodegradable containers 3) No special aircraft-equipment-corrosion problems 4) Multiple "hot spot" targeting with one aircraft 5) Increased payload, coverage, and speed to fire 6) All-weather/terrain aerial firefighting day or night 7) Computer-aided targeting 8) Bomblets falling true to target with an even burst Significant resources are spent each year at local, state and federal levels to fight wildfires. California alone spends $1.3 billion annually fighting wild land fires. The next phase of Precision Aerial Fire Fighting would include aircraft airdrop testing later this year. Based on analysis to date, this testing would verify that the PAFF system offers immediate containment of potentially devastating forest fires and pave the way for development of this innovative weapon in the war on fires. |

C-17s dropping water balloons on fires? Cool...
.... but in a Canadian aviation history book I read a while back, they talked about early aerial firefighting attempts, including dropping paper bags full of water on the fire. It delivered the water, but the impact of the bag often sent sparks flying everywhere, spreading the fire while putting out the centre bit of it. It seems to me that the C-17+water balloon could have the same flaw. The advantage would be that you could drop a whole LOT of the things, of course. Interesting, anyway. Anyone want to be that with the extra-destructive fires in California this year there'll be more interest in firefighting come next budget time in lots of places? (It was a bad year in BC, too, but we've had worse, and the rest of Canada seems to have gotten off fairly well...) Brian. |

How long would it take to fill, and keep refilling all these water balls?

Of course, the water bombs are one-time use only. I have visions of whole 'reservoirs' full of water bombs just waiting to be deployed in time of emergency. |

What would be the effect of one hitting a house/car/person? I think the
current "spray" that comes down is safer to all. -- Kevin McCue KRYN '47 Luscombe 8E Rans S-17 (for sale) -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

If you're going to be hanging around near/in large forest fires, water balloons will be the least of your worries. George Patterson If you're not part of the solution, you can make a lot of money prolonging the problem. |

In a previous article, Big John said:
If one fell on a fire fighter you'd have one dead fella. Which is why the article said: As with today's aerial firefighting, a ground safety fire commander would ensure ground personnel are clear of the airdrop zone and would direct airdrop targeting. Of course we know that ground commanders NEVER make mistakes, right? -- Paul Tomblin http://xcski.com/blogs/pt/ Some of you may have had occasion to run into mathematicians and to wonder, therefore, how they got that way. -- Tom Lehrer, "Tom Lehrer In Concert" |

This is a really good idea.....considering Bombardier is closing the
Canadair 415 water bomber plant in North Bay, Ontario, there ust be an easy replacement for new bombers "Paul Tomblin" wrote in message ...
